Know Your Truck
How Your Lift Truck Operates
Warning indicator lights are provided
for protection of four important
systems of your lift truck
1 Ammeter (Battery charging system)
2 Engine oil pressure
3 Water temperature (Engine coolant)
4 Transmission oil temperature
The ammeter warning light indicates
when the battery is receiving no charg-
ing current. The engine oil pressure
light indicates if a problem causes oil
pressure to drop below a safe level. The
water temperature light indicates that
the engine is overheating for some
reason. The transmission oil tempera-
ture light warns that the transmission
oil is too hot and damage can result if
operation is not stopped until the
reason for high temperature is cor-
rected.
The warning lights can be tested with
the key switch.
Turn the key switch clockwise to
the "run" position. The ammeter
and eng oil press lights should il-
luminate, and the fuel gauge nee-
dle should indicate fuel level.
The water temp and trans oil
temp lights are also illuminated
for checking when the key switch
is turned to the "start" position.
Note: If you don't want to start
the engine when checking these
warning lights, move the direc-
tional control lever from "neutral"
briefly only, while turning the key
switch to the "start" position.
After checking the lights, turn
key switch back to "off".
The hourmeter is controlled by engine
oil pressure. It operates only if the
engine is running when the oil pressure
has built up (increased) above a level to
start the hourmeter. Operation of the
hourmeter can be checked by watching
for movement of the indicator as it
rotates.

Before Operation
How To Perform The Daily Inspection
Check the function of the hydraulic
system with the hydraulic pump
(engine) running.
Pull back on the tilt control lever and
hold until the upright reaches the full
back tilt position. Push forward on the
lever to return the upright to the ver-
tical position. Release the lever.
CAUTION
MAKE SURE THAT THERE IS ADE-
QUATE OVERHEAD CLEARANCE
BEFORE RAISING THE UPRIGHT.
Pull back on the lift control lever and
raise the fork carriage to full height.
Watch the upright assembly as it rises.
All movements of the upright and fork
carriage must be even and smooth,
without binding or jerking motion.
Release the lever.
If the maximum fork height is not
reached, this indicates that there is an
inadequate (low) oil level in the
hydraulic sump tank, or severe binding
within the upright.
Push forward on the lift control lever.
Watch the upright as it lowers. When
the forks reach the floor, release the
lever.
